Application filed November 29, 1890. `Serial No. 373,081. (No model.)

Beit known that I, CHARLES F. WURsTER, a citizen of the United States, residing at the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Tempering-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of Which- Figure lis a plan view, the rock-shaft E and the upper shaft B3 being partially broken away. Fig. 2 is an end view, the driving-pulleys being removed. Fig. 3 is a transverse vertical section, as on the line 0c, Fig. l.

The nature of this invention isan apparatus of novel construction for'use more especially in the temperingof umbrella-ribs or the like. In the well-known mode of tempering such articles they are thoroughly commingled with a number of very hot metallic rods, aud upon reaching the proper temperature they are removed from the rods and plunged into a water-tank. Heretofore the commingling of the ribs and the rods has been eifected by rolling the same to and fro upon a suitable table by means of a heavy implement manipulated by the operator. This is a slow and tiresome operation, which requires some experience and muscular strength in order to practice the same with success.

The primary object of my invention is to provide asimple and eicient machine whereby the commingling of the ribs and heatingrods may be accomplished with ease and dispatch, said machine consisting in the combination of a series of rotating wheels or disks arranged in respect to each other and adapted concertedly to act upon a mass of ribs, 85o.,

interposed between the same, as hereinafter more fully described. f,-

The invention also comprises features of construction which will beduly pointed out.

Referring to the annexed drawings, A represents the frame-work of the apparatus, consisting of two substantial end cheeks a a', suitably connected and braced by stay-rods a2. Mounted within suitable boxes in the Y end cheeks are three parallel longitudinal from which mot-ion is imparted to others, as will hereinafter appear. Those ends of the shafts adjacent to the cheek a extend outwardly and carry coacting gears, the gear on the low or driving shaft B being a pinion b, which engages with two spur-wheels b b2 on the shafts B B2, respectively. The extended end of the shaft B also carries the pulleys C, to which motion may be communicated from a suitable source of power. The shafts B B2 are disposed in the same horizontal plane, or substantially so, and they have each fixed thereon at suitablel intervals apart a series of wheels or disks D, which in' this instance number five, although, if desired, a less or greater number .may be employed. The wheels D in one series align with those in the other series, but are out of contact therewith, as seen. The peripherie's of these wheels are serrated, milled, or otherwise roughened,`

for a purpose hereinafter explained.

Journ aled within boxes a3 on the end cheeks a ct is an upper longitudinal shaft E, which is represented in line, or nearly so, with the shaft B. This upper shaft has fixed on each end thereof, just within the adjacent endcheek, an arm .e. The free ends of the respective arms afford bearings for a longitudinal shaft B3, upon which is mounted, similarly to the lower shafts B B2, a series of wheels D', which, when in active position, lie just above and between the upper inner edges of the respective wheels in the two lower series, as clearly shown in Fig. 3.

On the proper end of the shaft B3 is keyed a spur-wheel h3, and on the adjacent end of the shaft E is loosely mounted a pinion or idler e2, which gears the said spur-wheel with the lower spur-wheel b.' The diameters of the like gears are the same-that is to say, the two pinions are, similar in all respects, and likewise the three spur-wheels. By this system of gearing it will be observed that when the main shaft is driven the shafts B, B2, and

B3, Withtheir respective series of serrated IOO indicated by the dotted lines in Fig. 3. The shaft E, turning or rocking in its boxes, per-- mits this to be done without disengagement of the loosely-mounted pinion e2 from the coacting spur-wheels. Assuming these upper elements to be in this idle position, the number of ribs r to be tempered, together with the highly-heated iron rodsr, are disposed upon the two lower series of wheels D, the ribs and rods being kept in position laterally by means of two loosely-surrounding rings F. (See Figs. l and 3.) The upper series of wheels D are then thrown down upon the mass, and upon motion being impartedto the driving-shaft the several series of serrated wheels are simultaneously and uniformly rotated, as above mentioned, and as a consequence their roughened peripheries bite and'intimately mixv and commingle the ribs and rods. This operation, while more positive and thorough in its results, takes much less time than formerly. v

I usually mount upon the shaft E near its ends inwardly-projecting plates G, respectively, which constitute positive stops or gages to prevent longitudinal displacement of the ribs and irons while being acted upon. These plates are fitted loosely to the shaft, so as to be adjustable lengthwise thereof, and they are furnished with set-screws g, which are adapted to fixthe plates at the predetermined points of adjustment. I make the plates adjustable in this way in order to provide for ribs and irons of various lengths.

To guard against the strainingor jamming of the gear-teeth bythe heavy Weight of the upper swingingshaft B3and its adjuncts when the parts are in the active position, I yprefer to form upon or secure to each of the end cheeks an inwardly-projecting stop s, which limits the downward movement of the adjacent arm e. Other means to the same end may be readily devised.

I claim as new and wislrto secure by Iletters Patentl. In a tempering-machine, the combination,with the supporting-frame,o f the shafts, the commingling wheels or disks thereon with serrated or roughened edges, and mechanism for rotating said shafts, substantially as de-v scribed.

the idler thereon engaging one of said spur-v wheels, the single upper shaft connected with said rock-shaft, and the spur-wheel on the latter gearing with said idler, together with the commingling wheels or disks upon said single and pair of upper shafts, respectively, substantially as described.

4. The combination, with the supportingframe, of the driving-shaft, the pinion thereon, the pair of upper shafts, the spur-wheels thereon engaging said pinion,the rock-shaft,

the idler thereon engaging one of said spurwheels, the single upper shaft connected with said rock-shaft, and the spur-wheel on the latter gearing with said idler, together with the commingling wheels or disks upon said single and pair of upper shafts, respectively, and the stop devices for limiting the descent of said single upper shaft and its connections, substantially as described.

5. The combination, with the supportingframe, of the lower shafts, the series of commingling wheels or disks thereon, the swinging upper shaft, the commingling wheels o1' disks thereon, and mechanism for rotating said shafts in concert, together with the adjustable end gages and means for fixing them at the predetermined points of adjustment, substantially as described.

In testimony whereof I have hereunto afxed my signature this 24th day of September, A. D. 1890.
